NEEDLE FOR BINDERS.

SPECIFICATION forming part of Letters Patent No. 707,482 dated August 19, 1902.

Application filed August 30, 1901. Serial No. 73,857. (No model.)

To all whom, it may concern.-

Be it known that I, EDDIE WILL,a citizen of the United States, residing at Bigstone, in the county of Grant, State of South Dakota, have invented certain new and useful Improvements in Needles for Binders, and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to needles for the knotting mechanism of grain-binders; and it has for its object to provide a needle wherein the twine will not be torn, while the life of the needle will be greatly prolonged, while the needle will be operated with greater ease than usual.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation of a needle embodying the present invention, a portion thereof being in section to show the frictionrollers. Fig. 2 is a transverse section through the roller and the front portion of the needle. Fig. 3 is a bottom view of one end portion of the needle and showing the spaced members bent into mutual contact to form a point.

Referring now to the drawings, the needle comprises the arcuate member 5, at points between the ends of which and projecting from the concave side thereof are the arms 6 and 7 of the pronged stem 8 of the needle. The needle is formed from a single blank of metal, the arcuate portion being bent upon itself to form the channel 9 in the inner side thereof, and in this channel are mounted the two grooved rollers 10 and 11, the roller 10 being disposed near to the front end of the needle, beyond which the sides of the channel are brought together to form the point,while the roller 11 is mounted at the end of the arm 6. At the free end of the stem of the needle is a bearing for the usual needle-shaft 12, and on the end of this shaft which projects through the stem of the needle is mounted the roller 14:.

In practice the twine is passed over the three rollers in the same direction as is usual in threading the needle; but the twine in running on the rollers is saved from the wear incident to being dragged over fixed surfaces, while the movement of the needle is easy and it experiences little Wear.

In practice modifications of the specific construction shown may be made and any 55 suitable material and proportions may be used without departing from the spirit of the invention.

What is claimed is- A needle for knotting mechanism comprising an arc-shaped head and astem formed integral from sheet metal, the metal of the head being bent upon itself to form spaced members and a connecting-web, the spaced members at the front of the head being bent inwardly into mutual contact to form a point, guide-rollers having shafts mounted in the spaced members within the head and a guideroller mounted upon the stem.

In testimony whereof I affix my signature 7c in presence of two witnesses.

EDDIE WILL.
